The ReactOS website has been completely redesigned. That in itself won't get your panties in a twist, however, the screenshots section might. They show just how far ReactOS has come: OpenOffice.org 1.1.4, MS Office 2003's setup, Unreal Tournament, Deus Ex, Flash Player, and much more. Note that some of those apps will only run in the latest SVN version.

Windows doesn't use the BSD stack. They may have started with it, but they have since rewritten it extensively. Even from the initial release they have used a different API to make it integrate into Windows, Winsock. Since Winsock 2 they have abstracted out to the API to support different network transports like IPX/SPX.

The BSD API is synchronous, and the Windows one is asynchronous. Even if ReactOS used the BSD implementation underneath they would still need to do quite a lot of work to make it usable to Windows apps.
